有时候对象中会包含数组、Map、Collection 等常见集合。java
为了存储的便利性,默认提供集合的相关支持。数组
特性和普通字段保持一致,若是指定注解转换,则以注解为准。ide
用于演示集合的对象测试
public class UserCollection { private String[] arrays; private LinkedList<String> lists; private Map<String, String> maps; private Set<String> sets; //Getter/Setter/toString() }
/** * 构建基于集合的测试列表 * @return 列表 * @since 0.0.3 */ private List<UserCollection> buildCollectionList() { UserCollection user = new UserCollection(); String[] arrays = new String[]{"a", "b", "c"}; LinkedList<String> lists = new LinkedList<>(Arrays.asList(arrays)); Map<String, String> maps = new HashMap<>(); maps.put("key", "value"); maps.put("key2", "value2"); Set<String> sets = new HashSet<>(); sets.add("set1"); sets.add("set2"); user.setLists(lists); user.setArrays(arrays); user.setMaps(maps); user.setSets(sets); return Arrays.asList(user); }
public void collectionTest() { final String path = "src\\test\\resources\\collection.csv"; CsvWriteBs.newInstance(path) .write(buildCollectionList()); }
arrays,lists,maps,sets a|b,a|b|c,key2=value2|key=value,set1|set2
public void collectionTest() { final String path = "src\\test\\resources\\collection.csv"; List<UserCollection> userList = CsvReadBs.newInstance(path) .read(UserCollection.class); System.out.println(userList); }
[UserCollection{arrays=[a, b], lists=[a, b, c], maps={key=value, key2=value2}, sets=[set2, set1]}]
为了保证 csv 以 ,
分隔的统一性。ui
集合使用 |
进行分隔,其中 map 的 key/value 分隔,用到了 =

在使用时要注意,不要包含上述的符号,不然会出现解析错乱。code
